Wireless Multimedia Sensor Networks Applications and Security Challenges

Abstract

The emergence of low-cost and mature technologies in wireless communication, visual sensor devices, and digital signal processing facilitate of wireless multimedia sensor networks (WMSNs). Like sensor networks which respond to sensory information such as humidity and temperature, WMSN interconnects autonomous devices for capturing and processing video and audio sensory information. WMSNs will enable new applications such as multimedia surveillance, traffic enforcement and control systems, advanced health care delivery, structural health monitoring, and industrial process control. Due to WMSNs have some novel features which stem the fact that some of the sensor node will have video cameras and higher computation capabilities. Consequently, the WMSNs bring new security of challenges as well as new opportunities. This paper presents WMSNs application and security challenges.

Cryptography in Wireless Multimedia Sensor Networks: A Survey and Research Directions

“…The operation characteristics and expected applicability of Wireless Multimedia Sensor Networks (WMSNs) have also opened new possibilities for security threats [5,6]. Sensed data may be stolen or altered during transmission or even unauthorized malicious sensors may inject false information into the network.…”

Identity-based Signature Proven Secure Under the Computation Linear Assumption

“…In wireless sensor network (WSN), there are many so-called motes that used to monitor the surrounded environmental data, such as sound, temperature, pressure, and so on [1]. Data collected by these motes is transmitted through wireless network.…”

Blockwise Frequency Domain Active Noise Controller Over Distributed Networks

“…Such networks have many advantages and applications compared to the wired networks [5,6] such as scalability and low computational cost. For the purpose of monitoring and transmission of multimedia content, Wireless Multimedia Sensor Networks (WMSN) [7] are available, which require increased computational cost, synchronization, data transmission and energy consumption because of certain characteristics of the multimedia signals [8]. A subclass of WMSN are the Wireless Acoustic Sensor Networks (WASN) [9,10].…”
